This version addresses the reviews from the OPS, Sec and ART
directorates.
One thing worth noting is we added the following editorial change:
A client offering the rrc extension MUST also offer the connection_id
extension [RFC9146]. A client offering the connection_id extension
SHOULD also offer the rrc extension, unless the application using DTLS
has its own address validation mechanism.
I'm calling this "editorial" even though it introduces one new MUST and
one new SHOULD, as I believe the intent was already impilcit, and thus
the text is merely reiterating an existing expectation.
Let us know if you disagree.
Note that the consensus call on the registry procedure changes for the
RRC Message Type registry ends today; shout if you have concerns with
that (late) change.
cheers!
